Finmeccanica’s Helicopter Division, the former AgustaWestland, has been for years one of the world’s leading companies in the design and manufacture of helicopters. The origins of the Italian Agusta and the British Westland date back to the beginning of last century.After more than 100 years, the British branch is still manufacturing helicopters at its main facilities in Yeovil (ICAO: EGHG) which includes a 1200 metre grass runway with 09/27 designation.The ATC managers at Yeovil / Westland airfield are currently involved in a project to implement new instrument approach procedures based on EGNOS. Tommy Brown, Senior Air Traffic Controller at Yeovil, talks about the project “Although quite unique because of the grass element, our runway

has been instrumented for years. We aim however at further improving operations with the new approach procedures, which will make use of the EGNOS APV-1 Service Level. The new procedures will be a huge improvement over the existing offset NDB approaches, not only because of the addition of the vertical guidance but also because of the reduced Decision Height.”The Company has recently signed an EGNOS Working Agreement (EWA) with ESSP SAS as EGNOS Service Provider, and expects approval of the LPV procedures in the coming months “We are about to finalise the Safety Case, as requested by our CAA. It will be submitted soon and it is our objective to obtain approval by autumn this year”, finishes Brown.

…that, on the 26th of January, EGNOS remained stable and properly synchronised to UTC whilst incorrect time information was broadcast by several GPS satellites? Check the full story here.

EGNOSSuccess Stories

Positioning under control makes the difference between success and failure in the 52 SUPER SERIES. This monohulls’ race brings together the best sailors in the world. Boat crews are made up of Olympic champions, America’s Cup winners and also sailors that have been enshrined in offshore sailing as the Volvo Ocean Race.

One of the turning points of the TP52 regattas is the start line. It is probably the trickiest time, when the Navigator must rely on the accuracy of its on-board computer. The start is an equation driven by speed, position and choice of the perfect place on the line. In the past, the battle in the start line was a process of learning and expertise in which the Helmsman, the Bow and the Navigator had to mentally calculate the right moment to pass the start line without skipping the kickoff time.

Afterwards, GPS and computers came on the scene: technology got on board. Nevertheless, positioning system errors made them doubt. The

advent of GPS brought a helpful tool to navigate but its errors, which in some cases could reach until 16 meters, were of no use when fighting for each centimetre on the start line.Fortunately now, with the inclusion of EGNOS in the navigation system of the sailing boats, Navigators have managed to substantially reduce the interval of error provided by GPS: EGNOS has been a great breakthrough for them. The position error has been extremely reduced, hence nowadays they can rely much more on computers to find out if they are well positioned in the start line.

The decisive step forward has been the arrival of EGNOS to the sailors’ tablets; a rather simple functionality in terms of implementation within the complex navigation systems used by professional sailors. SBAS is a feature that is usually configured in new navigation systems; therefore it is quite simple to take advantage of all the potential that EGNOS is offering.

Talking about

EGNOS benefitswith Vicente Laso Cortés

Vicente Laso Cortés is a Topographer and Engineer in Cartography and Geodesy and Civil works project designer. He has been involved for 17 years in civil engineering business and in particular he has dealt with all types of GPS devices during l the last 12. Since 2013 he is involved in forestry maintenance and inventories to feed GIS systems.

5E G N O S B U L L E T I N | I S S U E 1 8 | Q 1 2 0 1 6

You work for the company in charge of the maintenance of parks and  forest parks in Madrid capital. Please can you explain what activities are needed?

The company I work for, ORTIZ-EULEN, is in charge of managing and mantaining the forestal parks of Madrid. Those parks cover a great diversity of species, vegetal density and uses. The surface to be managed covers approximatley 2500 ha which includes both urban parks and forests.

Please can you explain what is the importance of doing inventories for such maintenance activities?

For an effcicent management it is needed to have information about the position and dimensions of each of the items to be mantained in order to define the corresponding management plans. From prunning to urban furniture conservation, up to reparation and maintenance of civil works.

Why EGNOS is a useful solution for inventories in natural environment?

Due to the great extension and great number of items to manage, it is neccesary to have highly versatile surveying equipments which provide the needed accuracy in complex environments for GPS. Nowadays thanks to the internet it is possible to obtain real time differential corrections, even for free, but where there is high tree density or when/where there is no GPRS signal, EGNOS corrections are extremely useful. New generation surveying equipment are easy to handle and transport and do not require wide knowledge of surveying and geodesy to operate with them in any environment.

What would be your message for companies interested in doing inventories in natural environments?

Resuming, the combination of different constelations allows surveyors to have more compact and easy equipment to perform accurate positioning. This brings a clear increase in the productivity in the generation of cartographic information.

When or where there is no GPRS

signal, EGNOS corrections are

extremely useful.

This is the xLS concept which aims at standardizing the way of flying an approach. Whatever the type of straight-in approach, the aircraft functions are designed to provide the crew with a similar and consistent operational solution. This concept provides not only the same guidance modes or displays to the crew but is also based on a similar avionics architecture.As part of this xLS concept, Airbus already proposes for all aircraft families:

·ILS (Instrument Landing System)·GLS (GBAS Landing System)·FLS (FMS Landing System) which extends the ILS look-alike concept to non-precision approaches (VOR, NDB, RNAV…)

On the 350, Airbus innovated by pushing the concept one step further with the SLS (Satellite Landing System). This new function uses GPS augmentation coming from SBAS systems such as WAAS or

EGNOS to allow the aircraft to fly down to LPV minima, as low as 200 ft DH and 550m RVR.Thanks to this SLS function Airbus is looking at maximizing airport accessibility for all its operators by providing a real “Precision Approach Service”. This includes in particular a geometrical vertical guidance which is fully independent from barometric setting error or temperature effect. The SLS function can enhance the airlines operations in multiple situations: at airports currently not having precision approach, at main runways as a backup of ILS (e.g. during maintenance) or at alternate airports in case of diversion. Airbus is therefore happy to see that the number of LPV approaches is increasing quickly all over Europe, with more than 250 procedures available today!

For example, in April Paris Charles de Gaulle will have LPV approaches with 200 ft minima. So during ILS antenna replacements, which are scheduled between 2016 and 2020, the A350 XWB could still have the capability to fly down to CAT I minima thanks to the SLS function.

Since the function was developed according to the xLS concept, there is no specific training required to fly a LPV approach. All pilots are trained to follow ILS beam and the SLS function provides

Thanks to the GPS constellation, aircraft navigation has significantly evolved over the past 20 years. Even if ILS remains the primary means for precision approaches, new technologies based on GPS now exist. Airbus has integrated these new technologies with an ILS look-alike interface which benefits from the ILS operational experience.

Thanks to this SLS function Airbus is looking

at maximizing airport accessibility for all its

operators by providing a real “Precision Approach

Service”.

a similar operational environment: the approach preparation is the same and the approach execution also. The aim of this concept is to have the crew immediately comfortable with the new approach function. And this was confirmed during A350 XWB flight tests campaign. In addition, pilots observed that the SLS signal was often better than CAT I ILS: aircraft position relative to the trajectory is always available and reliable, there are no false LOC or G/S side lobes and finally there is no interference linked to ILS protected area. In a nutshell, the pilot’s feedback is excellent!In terms of avionics architecture, the SLS function is hosted in the Multi-Mode Receiver (MMR). Through the GPS antenna, the MMR receives data from the GPS constellation and from the SBAS geostationary satellite. These data are then used to compute the LOC and G/S deviations which are sent to peripheral systems as if they were received from an ILS beam. The reference trajectory is based on a secured FAS, extracted from the navigation database. The MMR deviations are used by flight controls to guide the aircraft along the trajectory, and are also displayed on EFIS for pilot monitoring.In the end, the SLS development on the A350 XWB was a very positive experience and Airbus

is proud to have the first wide-body aircraft embedding the SBAS technology. This function provides high efficiency and flexibility to enhance A350 XWB operations. And it is already a success since more than 10 customers have selected this option: in a few years, more than 300 A350 XWB operating from all over the world will have the SLS capability! This new technology is unquestionably going to bring value in the precision approach domain.

PUBLICATION OF THE

EASA OPINION ON THE

PBN IMPLEMENTATION

IN EUROPE

According to the latest developments of the EASA rulemaking task RMT.0639, the Opinion on the Implementation of Performance Based Navigation in the European Air Traffic Management Network (EATMN) is expected to be published very soon. Based on the material published under the Notice of Proposed Amendment (NPA) 2015.01 for public consultation in January 2015, the Opinion will set the basis for establishing a mandate on ANSPs and Airport Operators to deploy APV procedures to all non-instrumental runway ends where, to date, there are only NPA procedures available, by the end of 2020.This opens a means to increment the penetration of LPV procedures (APV enabled by EGNOS) in Europe, increasing safety on a quite cost-efficient basis.

LOTS OF INTEREST ON

EGNOS DURING WORLD

ATM CONGRESS

A new edition of the World ATM Congress took place in Madrid between the 8th and 10th of March, and once again EGNOS raised a lot of interest among the event visitors.A workshop devoted to EGNOS for aviation was also held in order to provide the most up-to-date information about status and roadmap of the services, together with expected implementation trends for the coming years. Attendees had also the opportunity to learn how some European ANSPs have implemented their first EGNOS procedures during the last year.

RTCM SC-104

Monterrey in California was the designated place to hold the last Special Committee No. 104 on Differential Global Navigation Satellite Systems, within the Radio Technical Commission for Maritime Services (RTCM SC-104).

A two-days meeting on the 28th and 29th of January 2016 where the 21 attendees, including receiver manufactures, precision positioning services providers and survey organisations among others, discussed and agreed on the way forward for the recommended standards on DGNSS.ESSP attended this meeting and informed the audience about the GSA and ESSP plans on working together in the preparation of the draft “Guidelines for manufacturers for the implementation of SBAS in shipborne Receivers” in view of the IMO resolution MSC.401 on multisystem receivers. In particular the

draft Guidelines will describe the minimum set of SBAS messages to be processed to be compliant with requirements in IMO Res A.1046. This information was warm welcomed and the SC-104 chairman highlighted the potential interest of Special Committee 131 on this subject, which is working on the production of a standard on Multi-system Shipborne Navigation Receivers in advance of IMO, International Telecommunications Union (ITU), and International Electrotechnical Commission (IEC) standards.One of the main outcomes of the meeting was the agreement on the publication of a new version of the RTCM “Recommended Standard for Differential GNSS (Global Navigation Satellite Systems) Services, version 3.3”.

ERSAT EAV TRIALS IN SARDINIA

The main ERSAT EAV (ERtms on SATellite Enabling Application and Validation) objective is to verify the suitability of EGNSS (including EGNOS and Galileo early services) as the enabler of a cost-efficient and economically sustainable ERTMS signalling solution for safety railway applications.

In the frame of this project, two of the partners of the consortium, CEIT and ESSP, have performed a data campaign during five days in the Sardinia Trial railway site, between Cagliari and San Gavino, during the last week of January.

The objective of the data campaign performed between CEIT and ESSP was twofold. On one hand, CEIT is in charge of characterising the Sardinia Trial railway environment in terms of unknown blocking scenarios (EMI) and known blocking scenarios (natural GNSS blockers). On the other hand, ESSP acquired GNSS data both in static and dynamic modes in order to analyse EGNOS performance in this specific railway environment.

The ESSP measurement campaign was carried during one day with three return journeys. ESSP used part of its laboratory kit in order to perform this activity, a GNSS SiS recorder and a high-end GNSS receiver, which were installed onboard a diesel locomotive provided by RFI.

EGNOS data campaign results

Once the GNSS data were processed, they have been compared with the computed ground truth in order to have the horizontal accuracy for each test. The results were very promising, a good level of accuracy, on the order of 4 meters, was obtained in all return journeys. The only rejected points were those where the locomotive was passing through bridges being the only impact a higher horizontal accuracy error, between 6 and 15 meters, during less than 10 seconds; because of that, those outliers have a negligible impact on PVT solution on the test site.

…About STARS (Satellite Technology for Advanced Railway Signalling) project, a Horizon 2020 project under the 2nd Galileo call, which kicked off on the 23rd of February. This project aims to fill the gap between the need for safety critical applications and E-GNSS services through a characterisation of the railway environment and of GNSS performance assessments in that environment.

Did you know…?

The second day was kicked off by the introductory speech from Gian Gherardo Calini, Head of the Market Development unit at the GSA, who updated the attendees on the “European GNSS Adoption Opportunities in Transport with Focus on Rail”.

Mr. Per Enge from the Stanford University, talked about multipath in the railway environment and the need for international collaboration to explore the best techniques to solve this issue. Multipath errors

in the rail environment and the demanding safety levels to be achieved in railway signaling applications were the hot topics mentioned by most of the speakers.

The European Railway Agency was also represented by Mr. Angelo Chiappini, who described the process for production and adoption of ERA recommendations and the new responsibilities ERA will face as a result of the entry into force of the 4th Railway Package. He highlighted the potential strengths of satellite positioning and also the geographical constraints to face.

The Italian perspective and their presence in several ongoing and past initiatives was also addressed, together with the Italian Space Agency interest in boosting the development of GNSS based rail applications in Italy.
